NC-17 is the classification that succeeded the now outdated X rating for movies. Movies that receive this classification are considered too adult in nature for any children to see. No one under 17 is allowed into the movie. It contains several of the themes found in an R rated movie in abundance. It is not meant to classify a film as obscene, merely as one that children should not see. The qualifications for an NC-17 movie are that it goes beyond the scope of an R rated movie in its portrayal of the themes in question.
